• If you are trying to use Boolean operators, they must be ALL CAPS: ((nhung thoi) OR (nhung bi)) que van. viet tran trong ((cac thanh) OR (ban thanh)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung thoi) or (nhung bi)) que van. viet tran trong ((cac thanh) OR (ban thanh))".
• Adding a wildcard symbol may retrieve word variants: ((nhung thoi) or (nhung bi)) que van. viet tran trong ((cac thanh) OR (ban thanh))*.
